My religion requires that I work to move humanity and life out into the solar system and beyond, with all of human activities, including burial. Why should one tribe of Siberian-Americans' religion be privileged over mine?

But worse, neither ton or tonne is a unit of force; they are units of mass (2000 lbm, or 1000 kg). Force in the metric system would be in newtons or, for this rocket, meganewtons.
Have to say that it's very confusing when @elonmusk talks about "tons" of thrust. First, it's ambiguous whether it's 2000 lb, or a metric ton (which is generally spelled "tonne" (while at the same time discussing the mass of the vehicle in kg). 1/2

The idea that the IRA ever did anything close to what Hamas did is an insane comparison, though Want to know how many people died in this bombing? One. The IRA specifically tried to minimize civilian deaths while maximizing property damage for strategic reasons

His importance for NASA and human spaceflight over the decades was huge: George Abbey left us at the age of 91. Loved or hated, depending on whom you asked - but always remembered especially for being the driving force to open NASA for female and minority astronauts. RIP

Q. How many women does it take to screw in a light bulb? A. One. ONE!! And do you know WHY it only takes ONE? Because no one else in this house knows HOW to change a light bulb. They don't even know the bulb is BURNED OUT. They would sit in this house in the dark for THREE DAYS…
